Blend hemp seeds, lemon juice, chickpeas, water, garlic, olive oil and salt in a food processor or strong Ninja-type blender. Otherwise, first grind hemp seeds in coffee grinder (or spice grinder or pestle and mortar).
Blend for about 1 minute or until smooth. If you want thinner hummus, add a little bit more water.
To serve, put in a plate or a bowl, drizzle with some olive oil and sprinkle with paprika, red pepper flakes and chopped parsley or coriander.
